It's not a medical necessity denial because I have a denial for that on the same code for another patient and the denial (CO 50) states not medically
necessary as opposed to this denial which is a B15. There wasn't anything billed with it. My understanding of the denial is that something else should
have been billed with it. I have had this denial on a pathology code when I forgot to bill the pathology level CPT with a stain CPT. But I'm not familiar
enough with lesion removal to know what other code should go with it. I'll have to check with the office on what the diagnosis code is, I'm just doing
follow up for them and was given the mcr eob.
